So a Group 47, that's like the capacity of the battery? Say 110 Amp Hours?
What I was thinking is that 110AH battery is overkill. So I was wondering if something much smaller like a 30 amp hour battery would suffice?

|Smart Bob||I have two Group 47 AGM batteries in both of our smart cars that I acquired from O'Reilly's Auto Parts. I don't think they are lighter then a flooded cell group 47 battery. Also, the provision to attach the vent tube is provided on the AGM batteries that I have.|

Thinking about this vented tube and guessing it's because of the Lead Acid battery being used. If I used a lighter AGM battery, wouldn't need to worry about venting then right? And the lighter battery(plus tube removal) would just make it easier to work with plus less weight in the car.

|Foolios||Has anyone tried using a supercapacitor instead of a lead acid battery? The lighter weight seems like something that would really be beneficial.|

As for 12V battery reliability issues - could it be the constant 3-cylinder vibrations through the frame PLUS the harsh ride (limited shock absorption) that causes the grids to deteriorate?

|Yinzer||The battery Foolios linked to is an AGM (i.e. absorbent-glass-mat-non-spillable) battery. Is the Smart 12V battery an AGM or flooded type? Do you hear sloshing of liquid electrolyte when you remove it? I guess becasue of its unusual "indoor" location, it needs to be AGM . That explains some of the reliability issues Smart owners have reported. (AGM's are not as robust as flooded).|

|Smart Bob||Group 47 is the correct battery. Make sure you connect the vent tube. Also, to r & R the battery, you have to tilt the battery at the rear.|

Does this look right?
